UNDERGROUND ANCHOR.

Application filed August 16, 1917.

To all whom t may concern.:

Be it known that l, JOHN S. l/VHITEHEAD, a. citizen of the United States, residing at Sullivan, in the county of Sullivan and State of Indiana, have invented certain new and useful mprovements in Underground Anchors; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in underground anchors such as those used for bracing telephone poles, fence posts, and for preventing the latter from being pulled from the earth by the :tence when set in gulleys and the like.

The object of the invention is to provide an anchor of extremely simple and inexpensive construction, yet one which will be highly eiiicient and durable, and with this general object in view the invention resides in the novel features of construction and unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawings which form a part of this specification and in which:

Figure l is a side elevation of the improved anchor before setting thereof;

Fig. 2 is a similar View after the anchor has been set;

Fig. 3 is a top plan view; and,

Fig. el is a horizontal section on the plane of the line H of Fig. 2.

ln the drawings above briefly described, the numerals l designate a pair of arches, each formed of a single piece'of heavy wire, the crowns of both of said arches being twisted together as shown at 2 and forming a pair of eyes 3 to which the guy wire or the like el is anchored. As shown clearly in Fig. l, the two arches l are positioned in right-angularly located planes, and the free lower ends of their arms 5 are bent laterally outward at 6 to provide anchor members which are adapted to be forced into the earth. The arms 5 of each arch 1 converge downwardly, so that the size of the anchor at its lower end is normally substantially the same as the size at the upper end thereof. In this condition, the device is lowered into a hole in the earth as shown in Figs. l and 2 and the arms 5 are then spread so that the anchors 6 are forced into the earth. o

For the purpose of spreading the arms 5 Specification of Letters Eatent.

as above stated, a pair of rods 7 extend between the same, the ends of said rods being bent to form eyes 8 mounted slidably upon said arms. The rods 7 are of a length equal tothe width of the arches l at their upper ends, and it will be therefore obvious that. when these rods are forced downwardly along the arms 5, to the position 0f Fig. 2, said arms will be forced outwardly so that the anchor members 6 are embedded in the earth at the sides of the hole. Since this earth has been unmolested during the digging of the hole, it is solid and will thus effectively anchor the device. Additional anchoring is done, however, by the earth with which the hole is filled, such earth being packed as it is thrown in.

From the foregoing, taken in connection with the accompanying drawings, it will be obvious that l have provided a simple and inexpensive underground anchor which may be employed for numerous purposes, and that the device will be highly eiiicient and durable regardless of its use. Since probably the best results are obtained from the specific construction shown and described, such construction constitutes the preferred form of the anchor. I wish it understood, however, that within the scope of the invention as claimed, numerous minor changes may well be made without sacrificing the principal advantages.

I claim:

l. An underground anchor comprising a pair of arms connected at one end and tree at their other ends, said arms normally converging toward their free ends and having outwardly extending anchor members on said free ends, and a rod extending normally between the widely spaced ends of said arms and having eyes slidable alone" the latter, said rod being adapted to be 'orced along said arms to spread the same and force said anchor members into the earth.

2. An underground anchor adapted to be lowered into a hole and comprising an arch formed of a single piece of wire bent at its crown to form an attaching eye, the ends of said arch being bent outwardly to form a pair of anchor members, the arms of said arch converging downwardly, and a spreader extending between the widely spaced ends of said arms and adapted to be forced toward the other ends thereof to spread said arms and force said anchor members into the earth.
